A wood plank (length 4.6 m and mass 15.6 kg) is balanced between two saw horses, as shown in the figure below. One saw horse is positioned directly under one end of the plank, and the other is located a distance d1 = 3.4 m away. A child (mass 22 kg) walks along the plank, as if it were a balance beam. What is the furthest distance d2 (in meters) from the end of the plank that the child can walk before the plank tips and falls? Hint: When the plank starts to tip, one of the forces becomes zero.
